I own a pair of the lovely Adam A7X. Now I'd like to extend its lower range capabilities by buying an Adam Sub8 on eBay. The seller states that it is from 2008. But now I've noticed that the back panel with the connectors is located on the bottom of the subwoofer while the current pictures on the Adam website show the panel on the top.

So I asked myself if there are any other differences on those two Sub8 versions? I know there is an Adam Sub10 and Sub10 Mk II but afaik there's no newer Sub8.
